15.27. TPA3004D2
15.27.1. General Description
The TPA3004D2 is a 12-W (per channel) efficient, Class-D audio amplifier for driving bridged-tied stereo speakers. The
TPA3004D2 can drive stereo speakers as low as 4 Ω. The high efficiency of the TPA3004D2 eliminates the need for
external heatsinks when playing music.
Stereo speaker volume is controlled with a dc voltage applied to the volume control terminal offering a range of gain from –
40 dB to 36 dB. Line outputs, for driving external headphone amplifier inputs, are also dc voltage controlled with a range
of gain from –56 dB to 20 dB.
An integrated 5-V regulated supply is provided for powering an external headphone amplifier.
15.27.2.
Features
• 12-W/Ch Into an 8- Load From 15-V Supply
• Efficient, Class-D Operation Eliminates Heatsinks and Reduces Power Supply Requirements
• 32-Step DC Volume Control From 40 dB to 36 dB
• Line Outputs For External Headphone Amplifier With Volume Control
• Regulated 5-V Supply Output for Powering TPA6110A2
• Space-Saving, Thermally-Enhanced PowerPAD
